Before starting, compare items on your invoice with items
received. Carefully check through packaging material. If an
item is missing, please call Crutchfield at 1-888-955-6000.
IMPORTANT
1. The braided strap, if present in the vehicle, will be used as the ground for the replacement receiver.
Note: The ground is a flat flexible metal strap with a flat round terminal on the end. It is attached to the metal body of the factory radio with
a small bolt or screw. Some factory radios also have a two-wire plastic plug with thin insulated wires coiled around each other. These wires are
not the ground and should not be used or connected to anything. Leave them unplugged when installing a new receiver.
2. If your receiver does not have a dimmer or illumination wire, tape off the Orange wire.
3. On 1987-'88 Dodge Dakotas, the front negative leads may be connected with the rear negative leads in the Black plug. Check factory harness to
confirm. If so, an adaptor is needed. If the adaptor is not listed on your invoice, please call Crutchfield Sales at 1-800-955-3000 to order the
adaptor. Connect speaker wires following the instructions supplied with the adaptor.
4. If the vehicle has an amplified sound system, such as Infinity, connect the Blue wire from the Crutchfield harness to the amp remote wire of the
new receiver.
5. If the vehicle has the Infinity sound system, there may be a second wire, usually Black/Green, attached to the chassis of the factory radio with the
braided strap. If so, this is the ground for the Infinity speakers, and it must be attached to the braided strap and the replacement receiver’s
ground wire.
